HRV spectral parameters may discriminate hypotension-prone from resistant HD patients; leaves open utility for risk stratification pending prospective validation.
Do heart rate variability spectral parameters discriminate between hypotension-resistant and hypotension-prone patients during hemodialysis?
Heart rate variability spectral parameters can discriminate between hypotension-prone and hypotension-resistant patients during hemodialysis even when their hemodynamic behaviors are similar.
Cavalcanti et al. (1998) studied this question.
